Beatronic offer to modify the chambers with an advanced EMC shielding. The first model modified was the VT 4002 which became model VT 4002EMC. This version (1.00) was developed in cooperation with Nokia Mobile Phones in Denmark and the latest revision are currently supplied to 4 different mobile phone producers in +10 different countries around the world. Also manufacturers of wireless access points, car alarms, hearing aid, GPS systems, computer motherboard and similar product developer, has purchased the now famous VT 4002EMC test chamber.
The patent pending EMC shielding technique, developed especially for temperature and climatic test chambers, has allowed us to produce a considerable numbers units of this type since 2003. It is a niche market but all producers of radio wave electronics, potential needs to shut out the surrounding EMI noise and measure the sensitivity at different temperatures.

The VT 4002EMC is a Vötsch standard chamber with an EMC modification, developed in 2003 by Beatronic Supply ApS and in cooperation with Nokia Mobile Phones A/S in Denmark.
The chamber has a test space volume of 16 Liter and offers an optimum solution when limited space is available. The temperature range of the test chamber is -40°C to +130°C. Temperature conditioning efficiency renders this compact and yet very quiet chamber also suitable for universal applications. |
 |
Alternative to VT 4002EMC; fit the temperature test chamber, instruments and operator in a big EMC cage, not very flexible, or fit an EMC cage inside the temperature chambers test space but this will seriously compromise the chamber performance. The test chamber with EMC sealing incorporated in the test space walls, seams to be the best solution for most users. |
 |
In 2006 we also sealed a 340 litre test chamber with our EMC shielding technique, with great success and delivered finished product to a customer in China. Here the VT 4034EMC is undergoing the final EMC damping measurements. |
 |
VT 4002EMCs under production. Each unit will be submitted to a full functions test and re-calibration before shipment. We can implement the EMC seal both into used (RETROFIT) and new equipment, with equal good result. It is, however, recommended that used chamber are in good condition, with a perfect operation record and not much older than 2-3 years. |
 |
The concept is constantly undergoing further development and improvements to increase the EMC damping. Every time a construction change is introduced, the unit will undergo a full EMC test according to the norm IEC 61000-5-7 standard. (NOTE: important updated in 2009, owner/user of a VT 4002-EMC please download this document). The VT 4002 EMC has been tested from 0,5 up to 6 GHz with good results, almost 57dB damping on average and more than 75 dB in the 800-1000 Mhz area. |
 |
The entry module allows the user to supply the device under test with power and at the same time extract measuring result from the shielded space. The modules are exchangeable and can be manufactured to customer specifications. We offer a selection of entry modules designed to specific customer needs, in quantities of only one and up. Select between 9 & 25 pole D-sub connectors, SMA 24, single pole DC lead-troughs and USB2.0 connectors. |
 |
All lead-troughs are obviously filtered, so the they will not significantly compromise the basic shielding of the chamber test space.
Blank entry module allowing the end-user to do his own connections. |
 |
VT 4002EMC version 2, with entry modules in both left and right side of the test space. The module here holds 6 x 9 pole D-subs and 12 DC lead trough in one side and 6 x 24 SMAs on the other side. |
 |
The modules are interchangeable and can switched or changed to other versions. |
 |
Another special entry module. The SMA are the largest contributor to the thermal leak in the test chamber. It is always a good idea to reduce the numbers of connections and thereby increase the change rate and overall performance of the EMC chamber.
